A BDD tool for writing specifications using Given-When-Then template
The goal of pyhistorian is to write an internal Given-When-Then template using Python. The ideas came from JBehave, RBehave, Cucumber and others.
It's possible to write your stories in English and Portuguese, choose your preferred.
A good example of use [en-us, by default] follows (call this file calculator.py):
from should_dsl import *
from pyhistorian import *
class Calculator(object):
def sum(self, n1, n2):
return n1+n2
class SpecifyingMyNewCalculator(Story):
"""As a lazy mathematician
I want to use a calculator
So that I don't waste my time thinking"""
colored = True
template_color = 'yellow'
scenarios = ['SumScenario'] # optional
class SumScenario(Scenario):
@Given('I have a calculator')
def set_my_calculator(self):
self.calculator = Calculator()
@When('I enter with 1 + 1')
def sum_one_to_one(self):
self.result = self.calculator.sum(1, 1)
@Then('I have $value as result', 2)
def get_result(self, value):
self.result |should_be| value
if __name__ == '__main__':
SpecifyingMyNewCalculator.run()
Running:
$ python calculator.py Story: Specifying my new calculator As a lazy mathematician I want to use a calculator So that I don't waste my time thinking Scenario 1: Sum of 1 and 1 Given I have a calculator ... OK When I enter with 1 + 1 ... OK Then I have 2 as result ... OK Ran 1 scenarios with 0 failures, 0 errors and 0 pending steps
pyhistorian is at github.com
Due to DVCS I moved pyhistorian from Google Gode to github.com.
